[0002] Human life cannot live without paper, including household paper, sanitary paper, industrial paper, etc., and the demand is increasing year by year, and the requirements for paper rolling technology are getting higher and higher. Rewinding machines are generally used for: rewinding and slitting mica tapes, paper, and films, playing the role of splitting everything in two. They are often used to slit wide rolls, which plays an important role in the subsequent re-slitting. It is a special equipment for paper, mica tapes, and films.
[0003] At present, in the papermaking process, the rewinder sprays glue on the paper core tube during production, and starts running after sticking the paper tail. The paper core tube used in this production method can basically not be reused, and the amount of hot melt glue used is large, resulting in waste. Summary of the invention
[0004] The present disclosure is proposed in view of the above problems. The present disclosure provides a paper winding method of a rewinder, which can reuse the paper core tube used in the paper winding process of the rewinder.
[0005] According to one aspect of the present disclosure, a paper winding method of a rewinding machine is provided, comprising:
[0006] Passing the head of the paper web from the gap between the first bottom roller and the second bottom roller until the head of the paper web is adsorbed on the second bottom roller, wherein the second bottom roller is a vacuum roller with holes;
[0007] Using the first blowing device to blow the paper head until it is adsorbed on the paper core tube;
[0008] The paper roll crawling device is turned on. When the paper head crawls along the circumference of the paper core tube, the second blowing device is used to blow the paper head to be adsorbed between the paper core tube and the first bottom roller, and the third blowing device is used to blow the paper head to be adsorbed between the paper core tube and the second bottom roller;
[0009] The paper web is formed into a paper roll on a paper core tube.
[0010] In the technical solution provided in the embodiment of the present disclosure, first, since the second bottom roller is a vacuum roller with holes, before the next paper core tube starts to roll paper, the head of the paper web is passed through the gap between the first bottom roller and the second bottom roller, and the head of the paper web can be adsorbed on the second bottom roller. At this time, the first blowing device above the first bottom roller is used to blow the head of the paper web to be adsorbed on the paper core tube. Then, the paper roll crawling device is turned on, and in the process of the head of the paper crawling along the circumference of the paper core tube, the second blowing device located above the second bottom roller is used to blow the head of the paper to be adsorbed between the paper core tube and the first bottom roller, and then the third blowing device located below the gap between the first bottom roller and the second bottom roller is used to blow the head of the paper to be adsorbed between the paper core tube and the second bottom roller. At this time, in the process of the head of the paper continuing to crawl, the head of the paper can be rolled into the paper core tube by the following paper web, so that the whole paper is smoothly rolled on the paper core tube, and the paper web is formed into a paper roll on the paper core tube, so as to achieve the purpose of the paper core tube without spraying film. At the same time, the paper rolls are sent to the post-processing department. After production according to the specifications, since there is no glue on the paper core tube, the paper core tube can be recycled back to the winding machine for repeated use. This not only reduces the use of hot melt adhesive, but also increases the number of times the paper core tube is reused, thereby reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Human life cannot live without paper, including household paper, sanitary paper, industrial paper, etc., and the demand is increasing year by year, and the requirements for paper rolling technology are getting higher and higher. The paper machine rewinder is one of the important equipment in the papermaking industry. It is mainly used to slit and rewind large-diameter paper rolls according to specific specifications to make them into small-diameter paper rolls that meet market demand. The rewinder can adjust the width, tightness and diameter of the paper roll to ensure the quality and appearance of the paper roll.
[0022] At present, in the papermaking process, the rewinder sprays glue on the paper core tube during production, and starts running after sticking the paper tail. The paper core tube used in this production method can basically not be reused, and the amount of hot melt glue used is large, resulting in waste.

[0026] It can be understood that the first bottom roller 100 can be defined as the front bottom roller in the rewinding device of the rewinder, and the second bottom roller 200 can be defined as the rear bottom roller in the rewinding device of the rewinder. The paper core tube 600 can be placed in the middle gap above the first bottom roller 100 and the second bottom roller 200. Before the next paper core tube starts to reel paper, the head of the paper web can be passed between the first bottom roller 100 and the second bottom roller 200 from below the gap between the first bottom roller 100 and the second bottom roller 200.

It can be understood that the controller can be a chip with signal processing capability, such as a processor in a computer device.
[0035] Each operation in the above method disclosed in the embodiment of the present disclosure can be completed by an integrated logic circuit of hardware in a processor or an instruction in the form of software.

[0036] In an optional manner, the rewinding system of the rewinder of the embodiment of the present disclosure further includes a paper kicking device 900, which is used to remove the previous paper roll.
[0037] In an optional manner, the rewinding system of the rewinder of the embodiment of the present disclosure further includes an ejector mechanism, which is located at both ends of the paper core tube, and the ejector mechanism is used to fix the paper core tube 600 after the paper core tube 600 enters the operating position.
[0038] Exemplarily, the rewinding system of the rewinding machine of the disclosed embodiment further includes a plurality of introduction rollers 1000, which are located behind the second bottom roller 200, and the introduction rollers 1000 are used to introduce the paper web into the gap between the first bottom roller 100 and the second bottom roller 200 in a parallel direction.
[0039] Based on the above rewinder paper system, Figure 2 The schematic diagram of the process flow of the paper rewinding method of the rewinding machine of the embodiment of the present disclosure is shown. Figure 2 As shown, the paper rewinding method of the rewinding machine of the embodiment of the present disclosure includes:
[0040] Step 201: Pass the head of the paper web from below the gap between the first bottom roller and the second bottom roller until the head of the paper web is adsorbed on the second bottom roller, wherein the second bottom roller is a vacuum roller with holes.
[0041] In practical applications, firstly, since the second bottom roller is a vacuum roller with holes, before the next paper core tube starts to roll paper, the head of the paper web can be directly adsorbed on the second bottom roller 200 after passing through between the first bottom roller 100 and the second bottom roller 200.
[0042] Step 202: Utilize the first blowing device to blow the paper head until it is adsorbed on the paper core tube.
[0043] In practical applications, at this time, the first blowing device 300 above the first bottom roller 100 can be used to blow the paper head to be adsorbed on the paper core tube 600.
[0044] Step 203: Turn on the paper roll crawling device. When the paper head crawls circumferentially along the paper core tube, use the second blowing device to blow the paper head until it is adsorbed between the paper core tube and the first bottom roller, and use the third blowing device to blow the paper head until it is adsorbed between the paper core tube and the second bottom roller.
[0045] Exemplarily, after the paper head is blown and adsorbed on the paper core tube 600, the paper roll crawling device is turned on. During the circumferential crawling of the paper head along the paper core tube 600, the second blowing device 400 located above the second bottom roller 200 is used to blow the paper head to be adsorbed between the paper core tube 600 and the first bottom roller 100, and then the third blowing device 500 located below the gap between the first bottom roller 100 and the second bottom roller 200 is used to blow the paper head to be adsorbed between the paper core tube 600 and the second bottom roller 200.
[0046] Step 204: Form a paper roll on the paper core tube.
[0047] For example, when the paper head is adsorbed between the paper core tube 600 and the second bottom roller 200, the crawling speed of the paper roll is increased. During the process of the paper head continuing to crawl, the paper head can be rolled into the paper core tube 600 by the following paper web, so that the whole paper web is smoothly rolled on the paper core tube 600, and the paper web is formed into a paper roll on the paper core tube 600, so as to achieve the purpose of not spraying glue on the paper core tube. At the same time, the paper roll is sent to the post-processing department, and after being produced according to the specification requirements, since there is no glue on the paper core tube, the paper core tube can be recycled back to the winding machine for repeated use, which not only reduces the amount of hot melt adhesive, but also increases the number of times the paper core tube is reused, thereby reducing production costs.
[0048] In an optional manner, the embodiment of the present disclosure uses the first blowing device to blow the paper head to be adsorbed on the paper core tube, specifically including: first, using the first blowing device to blow the paper head to be adsorbed between the paper core tube and the paper pressing roller. Then, using the paper pressing roller to press the paper head between the paper pressing roller and the paper core tube.
[0049] In specific implementation, when the paper head of the paper web is adsorbed on the second bottom roller 200, the first blowing device 300 is used to blow the paper head until it is adsorbed between the paper core tube 600 and the paper pressing roller 700, and then the paper pressing roller 700 is dropped until the paper pressing roller 700 presses the paper head between the paper pressing roller 700 and the paper core tube 600. Thus, the paper pressing roller 700 can be used to press the paper head tightly on the paper core tube 600, avoiding the problem of the paper head falling, and also laying a foundation for the subsequent paper head to continue to crawl and wrap around the paper core tube 600.
[0050] In an optional manner, the embodiment of the present disclosure uses the first blowing device to blow the paper head until it is adsorbed between the paper core tube and the paper pressing roller, and the method further includes: firstly dropping the paper pressing roller 700 until the distance between the paper pressing roller 700 and the paper core tube 600 is a preset distance. It can be understood that the preset distance can be the initial distance between the center of the paper pressing roller 700 and the center of the paper core tube 600, and the initial distance can be 20 cm to 25 cm.
[0051] Exemplarily, the disclosed embodiment utilizes a paper pressing roller to press the paper head between the paper pressing roller and the paper core tube, specifically including: dropping the paper pressing roller 700 to contact the paper core tube 600 until the paper pressing roller 700 presses the paper head between the paper pressing roller 700 and the paper core tube 600.
[0052] In one achievable manner, the paper winding method of the rewinder of the disclosed embodiment also includes: when the paper roll needs to be replaced, using a paper cutting knife to cut the paper web passing through the gap between the first bottom roller and the second bottom roller, and the paper head of the cut paper web is adsorbed on the second bottom roller.
[0053] In practical applications, the paper cutter 800 can be used to cut and separate the remaining paper web from the previous paper roll after the previous paper roll is formed, thereby obtaining the previous paper roll. At the same time, the head of the cut paper web can be adsorbed on the second bottom roller 200, thereby continuing the paper rolling process of the next paper roll.
[0054] Illustratively, before the disclosed embodiment uses a paper cutter to cut the paper web passing through the gap between the first bottom roller and the second bottom roller, the method further includes: raising the angle of the paper cutter to 24° to 35°.
[0055] In specific implementation, after the last roll of paper is formed, before the paper cutter 800 is used to cut and separate the remaining paper web from the last roll of paper, the paper cutter 800 can be raised to an angle of 24° to 35°, and then the paper web is cut. At this time, the length of the paper head of the cut paper web adsorbed on the second bottom roller 200 can be ensured to be as long as possible, so that when the first blowing device 300 is used to blow the paper head to be adsorbed on the paper core tube 600, the paper head can pass between the paper pressing roller 700 and the paper core tube 600.
[0056] In practical applications, the control program can be stored in a computer device in advance, and then the computer device can be used to send a start command or a stop command to the first bottom roller 100, the second bottom roller 200, the first blowing device 300, the second blowing device 400, the third blowing device 500, the paper pressing roller 700, and the paper cutting knife 800, so that the start and stop of the first bottom roller 100, the second bottom roller 200, the first blowing device 300, the second blowing device 400, the third blowing device 500, the paper pressing roller 700, and the paper cutting knife 800 can be directly controlled by the electronic device to realize the process of winding paper of the rewinder.
[0057] Illustratively, after the embodiment of the present disclosure uses a paper cutter to cut the paper web passing through the gap between the first bottom roller and the second bottom roller, the method further includes: removing the previous paper roll using a paper kicking device.
[0058] For example, after the paper core tube 600 enters the pre-production position without glue spraying, the paper kicking program is started to kick out the last completed paper roll, thereby providing paper rolling space for the next paper core tube.
[0059] Exemplarily, the paper winding method of the rewinder of the embodiment of the present disclosure further includes: using a ejector mechanism to install the paper core tube above the gap above the first bottom roller and the second bottom roller.
[0060] In one example, the rewinding method of the rewinder of the embodiment of the present disclosure further includes: using an introduction roller to introduce the paper web into a parallel direction, and then entering the gap between the first bottom roller and the second bottom roller. It should be understood that the introduction roller can be arranged behind the second bottom roller.
[0061] It can be understood that in the paper winding system of the rewinder of the embodiment of the present invention, the winding direction of the paper web on the paper core tube 600 is clockwise. The paper web is first introduced into a parallel direction by using the introduction roller 1000, and then enters from the gap between the first bottom roller 100 and the second bottom roller 200, and then starts to be wound from the side of the paper core tube 600 close to the second bottom roller 200. The paper web crawls around the paper core tube 600 in a clockwise direction, thereby completing the paper winding process of the rewinder.
[0062] Example:
[0063] 1. Stop the paper core tube glue spraying procedure;
[0064] 2. Adjust the paper cutter angle in the program to 24 to 35 degrees;
[0065] 3. Add a first blowing device on the first side of the paper pressing roller, a second blowing device on the second side of the paper pressing roller, and a third blowing device at the lower paper cutting knife;
[0066] 4. After the paper core tube enters the pre-production position without glue spraying, the paper kicking program starts, and the paper kicking device kicks out the previous set of paper. At the same time, the paper core taking program starts, and the vacuum suction cup sucks up the paper core tube and transports it to the top of the gap between the first bottom roller and the second bottom roller, and puts it into the running position;
[0067] 5. The paper cutter automatically rises to a 35-degree angle to cut off the paper width of the previous paper roll. According to the program setting, the cut paper head is adsorbed on the second rear bottom roller. At this time, the paper head is not long enough, and the second bottom roller starts to crawl, driving the paper head to crawl;
[0068] 6. The paper core tube is lowered to the middle position above the first bottom roller and the second bottom roller. At this time, the paper head is attached to the second bottom roller, and the ejectors on both sides enter the running position, holding the two ends of the paper core tube to fix the paper core tube;
[0069] 7. The paper pressing roller starts to fall. When it falls to a height of 20 cm from the paper core tube, the first blowing device is started. The first blowing device on the first side of the paper pressing roller blows the paper head from the second bottom roller to the paper core tube. The end of the paper head is located between the paper core tube and the paper pressing roller.
[0070] 8. Because the glue spraying is cancelled, the paper head cannot stick to the paper core tube. At this time, the paper pressing roller continues to fall, pressing the paper head between the paper pressing roller and the paper core tube. At this time, the first blowing device on the first side of the paper pressing roller stops;
[0071] 9. The crawling program starts, the second blowing device on the second side of the paper pressing roller and the third blowing device at the paper cutting knife are turned on at the same time, the paper head runs in a clockwise direction at a speed of 5 m / min, and the second blowing device on the second side of the paper pressing roller blows the paper head into the space between the first bottom roller and the paper core tube in the running direction;
[0072] 10. The paper head continues to move forward, and the third blowing device at the paper cutting knife blows the paper head into the space between the paper core tube and the paper web at the second bottom roller. The whole paper is smoothly rolled on the paper core tube. After 6 seconds, the speed is changed to 10 m / min, and it crawls for 30 seconds. The speed is increased to the operating speed of 1850 m / min until the specified length is rolled. Repeat action 1) to complete a complete non-film-spraying paper process.
[0073] The rewound paper rolls are sent to the post-processing department. After production according to specification requirements, because there is no glue on the paper core tube, the paper core tube is recycled back to the rewinder and the rewinder is used repeatedly, which reduces the use of hot melt adhesive, increases the number of times the paper core tube is reused, and reduces production costs.
[0074] In summary, in the rewinding system of the embodiment of the present disclosure, since the second bottom roller is a vacuum roller with holes, before the next paper core tube starts to roll paper, the head of the paper web can be passed through the gap between the first bottom roller and the second bottom roller, and the head of the paper web can be adsorbed on the second bottom roller. At this time, the first blowing device above the first bottom roller is used to blow the head of the paper web to be adsorbed on the paper core tube. Then, the paper roll crawling device is turned on, and in the process of the paper head crawling along the circumference of the paper core tube, the second blowing device located above the second bottom roller is used to blow the head of the paper to be adsorbed between the paper core tube and the first bottom roller, and then the third blowing device located below the gap between the first bottom roller and the second bottom roller is used to blow the head of the paper to be adsorbed between the paper core tube and the second bottom roller. At this time, in the process of the paper head continuing to crawl, the head of the paper can be rolled into the paper core tube by the following paper web, so that the whole paper can be smoothly rolled on the paper core tube, and the paper web is formed into a paper roll on the paper core tube, so as to achieve the purpose of the paper core tube without spraying film. At the same time, the paper rolls are sent to the post-processing department. After production according to the specifications, since there is no glue on the paper core tube, the paper core tube can be recycled back to the winding machine for repeated use. This not only reduces the use of hot melt adhesive, but also increases the number of times the paper core tube is reused, thereby reducing production costs.
